mpgoveMeNT 1N STEAM-mp2s' Eon REVERSING STEAM-ENGINES.

The Schedule referred'toi these Letters Patent `and making part of the same.

. myself and Joseph F.` Gent; c and Ldo hereby declare, ,that the following isa full', clearand exact description p of the construction` and operation of the same, reference being hadl to the accompanying drawings, and to the letters of` reference marked thereon.

The nature of my inventionconsists in providing the valve-box e, the working-jointbetween the pipe b,

, fand the stern ot' the valve inthe valve-box e; also the i working-joints c, between the pipes g and the' stems of the valvesin the valye-boxes d, as shown in Figure "1, perspective view, thereby obviating the necessity of the plates andlset-screws-above theyalves, as set forthin the patent above Vreferred to.`

` Figure 2 is avertical sectional view, in which the .course of the steam is indicatedby the arrows;

The pipes'a oi" b may either' -be connected with the boiler, as may be desired. f

" Incase the pipell is'connected with the boiler, the course of 4the steam would Vbe the reverse of that indicated by the arrows.

" In Figure 4, b is the stemof the valveywhichstem has an opening throughit, connecting with the open-Y ings 3 in theface of the valve k.

One'of these openings, with` one of the grooves 4,

connects with the' pipes f g on the right,- and the other with the pipes fg on the left hand, as in fig. 1.

' Figure 3 represents a valve, such as works within the-valveboxes d. Y A ThisA valve has [a hollow stem, g, which connects with the pipes g, perspective`view.

Figures 5 ,and 6 represent'the working-joints between the pipes and valve-stems, in which 8 is a ring, fastened upon the end of the valve-stems. ,This is snrrounded bythe ling 7. f

The partfrepresented in iig. 6 is brought tothe porf tion of fig. 54 marked 5, and securely bolted, thereby forming a working-joint.

' The screws O are forthe purpose ofikeeping the valves to their seats, should they not'exactly t the 'top of the valve-boxes, and also to prevent the springing of the stemsof the valves. Y. 1* What I claim, and desire to secure by Letters Pat- .1. The arrangement of thevalve-box e, the joint h, between the pipe b and the stem of thevalve k, 4and. the joints c, between the pipes y and the stems of the valves in the valve-boxes d. Y 2. The hollow stems o'f the valves 1a and Z, substantially asshown and.described. JOSEPH B. PEDRIOK. Witnesses:
